Green Monster

My son wanted a baseball party for his 8th birthday, and since we're Red Sox fans I figured how can we have a baseball party with a home run derby without the green monster in left field. It was made out of two sheets of plywood, triangle stands made out of leftover 2x4s and 2x6s. Outdoor paint, print outs for lettering with a clear over them, and velcro to put on the placards and numbers for the home run derby.
